It is really amazing to see the difference of quality between the Canon video files and RAW files from Magic Lantern. The dynamic range is huge and there are lot of leeways to play around with the highlight and shadows. The freedom of colour correction is enormous. Shooting RAW with Magic Lantern is surprisingly simple, despite of the fact that the length of the video shoot in lower end Canon DSLRs are shorter compared to the high end dslrs. I've included a comprehensive RAW workflow at my upcoming Magic Lantern tutorial. The duration of that workflow based tutorial is around 40 minutes. Here is the video that I shoot during my visit to Dundle Door, Dorset.
Magic Lantern RAW Video.
I'm really delighted to inform you all that my tutorial on Magic Lantern is in final stage and will be up on the site within a week. This three hours training is a comprehensive one covering all the audio and video features of Magic Lantern. The tutorial covers both standard version 2.3 and Nightly Build. Therefore you'll have all the current updates and information in this tutorial. From audio recording to exposure settings, overlay features and Movie recording, this tutorial covers all these sections and you’ll find a wealth of information that you can make use of to unleash your creativity. Over the years, hundreds of videographers, and filmmakers have made use of Magic Lantern and produced amazing videos and films. In this tutorial I’ll demonstrate all the features that you need to shoot quality video; I’ll give you my recommendations and provide you some workflows for RAW, time-lapse and HDR video. I’ll also give you detail information on how to record quality audio , how to install customer picture style and how to install customer crop-marks. Overall it is comprehensive tutorial on Magic Lantern up until now.

Sony's A7s is out for months now and so many reviews and videos out there on the net. Therefore now we can say very clearly what this camera is truly capable of.
I love sensitivity, Sony delivered that in A7s. The capability of capturing usable frames in very low light in this camera is incredible. Philip Bloom showed us how much capable A7s is in capturing low light, it is simply mind blowing. The S-Log is brilliant feature although there are some limits in using it. The ergonomics is not too bad. Looks like mirrorless design is going to be the dominant feature for the future dslrs. However there are some tradeoffs. I'll discuss two of them.
No internal 4K recording:
A user has to spend around $2000 extra for a 4K external recorder on top of the camera price of $3000 to shoot 4k video which makes a minimum system costs around $5000. This fact is being ignored by many. There is only 8 bit 4:2:2 colour depth for both HD and 4K recording which may cause some issues while grading.
Rolling shutter/jello effect:
It is terribly visible even for simple moves. Even after doing some tweaking, as suggested by Philip Bloom in his review, the jello effect can still be very much visible. Although the full frame sensor is very good for low light but the jello effect is a huge tradeoff. In fact this camera can be useless in shooting action movie/video where you need be handheld most of the time and do lots of panning. Interestingly neither the promotional video released by Sony, nor in the video reviews made by Philip Bloom and Den Lennie have any movement at all. The reason is unknown. Maintaining focus is likely to be challenging in this camera along with other full frame dslrs.
Looks like Den struggled a bit in maintaining focus while shooting on the boat. At around 2.18 of the video below he seemed to lose focus.

Finally the trailer is out and feature film is at the queue in film festivals . Director Jack Everit has finally delivered his promise. He is working hard to make it to the theater. It was a snowy morning in February 2012 when we started shooting the film. Being one of the cinematographers, it was not an easy task to carry on the project for almost two and half years. Now after watching the trailer it seems all the pains and hard work had been paid off.

Sony FDR - AX100Sony announced its fist consumer level 4K camcorder Ultra-HD FDR-AX100 Handycam in this year's CES at $2,000. This is indeed an aggressive push from Sony to make a head start in the 4K race at consumer level. Apart from the price, there are few things that are very interesting about this camcorder. The sensor used is a 1" Exmor R CMOS sensor which is around 8x larger than the typical camcorders. This is important for many reasons and one of them could be that the current DSLR generation has got used to in taking advantage of larger sensors. They love beautiful shallow depth of field, beautiful bokeh and other creative choices offered by the larger sensor. The lens used in this camera is also interesting. Sony used Zeiss Vario Sonnar T* lens with 12x optical zoom plus 24x digital zoom. The focal length of this lens is 29 to 348mm. The aperture is 2.8 to 4.5. Sony said that the camcorder boasts with Optical SteadyShot image stabilization with Active Mode which delivers smooth video. A 3-Way-Shake-Canceling is also there which adds electronic roll stability for even smoother results. It lets you capture 4K 3840x2160 video at 24 and 30 fps. You can also record in 1920x1080. The recording codec used are XAVC S for 4K and AVCHD for normal HD video. It has a 3.5" XtraFine LCD touchscreen and a high-contrast 0.39" OLED EVF. Among other notable features, the camcorder has a USB 2.0 port, Micro HDMI output, and a Composite Video output. The composite video output is important for professional use. There are also Built-in Wi-Fi and NFC support that lets you use your smartphone or tablet to control the camera, as well as wirelessly transfer files to your mobile devices and your computer. These are all looks good for a 4K camcorder at $2,000 price point. However, the question is whether these specs will satisfy the growing indie makers or videographers?
